L-Carnitine

Amino-acid derivative (not a peptide) that shuttles fatty acids into mitochondria for energy production; widely sold as an oral supplement and as an injectable component of "lipotropic" shots.

CategoryFat Loss / Metabolic
Typical routeOral
Half-life~15 hours (oral); shorter when injected
Common dose range500-2000 mg/day oral; 50-100 mg per injection in lipotropic blends
Typical cycle lengthOngoing

BioHack Track models L-Carnitine at a half-life of 15 hours, so every dose you log is decayed against that curve and the app shows what is still circulating — not just what you typed.

Reconstitution

Oral capsules/liquid need no prep; injectable forms are typically pre-mixed.

Storage

Store at room temperature.

Cautions

Generally well-tolerated; evidence for meaningful fat-loss effects from supplementation alone (absent a calorie deficit) is modest.

Track L-Carnitine in BioHack Track. Half-life, dose range and route come pre-filled from this library — log a dose and the app counts your vial down, models what is in your system, and puts it on the same chart as your labs and body composition.
